Let me add that there is no arbitrary limit to the size of a grid in the code. The memory size of the workstation (and/or the value set in Preferences) will basically set the limit. For large grids/images, using a 64-bit machine with lots of memory is a necessity these days (there is a limit of abou...

These symbols were included in the special "wmo" Hershey Font developed for VisAD which closely followed the GEMPAK code at the time. Since these are "stroke-generated" symbols, the associated Hershey Font can be edited to change the symbols for the 9 items -- it would be more di...

For point obs, you can use the Jython len() method to get some of this information. For example, from the SFCHOURLY reports, I get a "getType(data)" listing that tells me the Type of the data looks like this: index -> ((Latitude, Longitude, Altitude), Time, (TYPE, NREC, MOD, HMS, CIGC, CC1...

There is also a plug-in called "Jython Control" which provides a template to get people started in writing Jython code that gets "called" when the user does some interaction with the main display (for example, move the probe). The template is just that -- it illustrates the use o...

I believe you need "SIZE=ALL" to get the entire image. The 640x480 is the default size when the "frame size" (a McIDAS-X construct) is unknown...it's a throw-back to the Good Ol' Days... I do not know if there is a word in the AREA Directory that indicates, for "tracked imag...

The problem is that the "color-by" field is the same as one of the components used to create the vectors and the underlying library cannot create a new Data object using the same field twice. I suggested that the user create a new formula with just one line: combineFields ( grid, newName(c...

A user reported that he was trying to run McIDAS-V inside a firewall, and that only the Main Window would appear -- the Data Explorer window never showed up, nor could he bring it up by clicking on the "V" icon. The solution to this is to go to the User Preferences window (from Edit --> Pr...

Most gridded data can be saved in a netCDF file using the method in the Jython library:



This creates a netCDF file that usually can be read in using the "file" chooser and selecting a Data Type of "Grid files(netcdf/...").

...I get one blank line inserted into the history after each command I type. So, when I hit the up arrow to navigate backward through my history I get a blank line before the actual command I had typed. Does anyone else see this behavior? (In nightlies from the last 2 weeks). -Mike Mike -- I see th...
